I'm trying to create a place for these PCBS to mount onto:
but I don't know where to position the mounting holes for the PCB so that it can be screwed onto a standoff because the documentation for them only states how long each side of it is.
I already bought the PCBs and have a circuit soldered to one of them so I can't buy better documented ones. I've currently tried printing screw holes at varying distances to test for the ideal distance but the plastic bends too much to be reliably compared to the ideal unbending mounting board, so I would need to waste dozens of grams of plastic per failed hole distance test to make thick prints to accurately test.
Anyone here have a solution to this?
